In the past few days, several people have asked me the same question: Claude Code is great, but the official version requires a subscription, and the API is prone to restrictions. Is there a way to run it at low cost?
My answer is straight: clawdfree. It's based on Claude Code v2.1.88, with the core changes being the removal of account subscription checks and the integration of a proxy API route. Simply put, you don't have to pay the $20 monthly fee or deal with credit cards; you just need a proxy API Key to run it.
Let me walk through a specific scenario so you'll know exactly how to use it.
Scenario: Quickly Generate Documentation for Your Project with clawdfree
I have a React component project that has been sitting with a bunch of uncommented code and no README. I didn't want to write it line by line myself, so I wanted Claude Code to handle it.
Step 1: Get clawdfree and Configure the API
This project can be found on GitHub; just clone it. The dependency installation step is nothing special – use npm or yarn like the official version.
The key is in the configuration. It reads the environment variable ANTHROPIC_API_KEY by default, but you can directly set this variable to your proxy API Key, as long as the proxy provider supports the Anthropic protocol. I tried one proxy, filled in the endpoint they provided, and plugged in the Key.
export ANTHROPIC_BASE_URL=https://your-proxy.com/v1
export ANTHROPIC_API_KEY=sk-your-key-here
You should verify that your proxy connection is stable. In my use, there were occasional timeouts and retries, but it didn't affect much.
Step 2: Start clawdfree and Begin Working
You don't need to log into any Claude account; just run it directly in the project directory:
clawdfree
The first startup will ask you to confirm which files to scan, then Claude Code starts working. I told it to 'add JSDoc comments to all components under src/components, keep the English concise.' It scanned the code step by step, understood the logic, and generated comments. The whole process took about three minutes.
Here's a detail: clawdfree uses claude-sonnet-4-20250514 by default, which is powerful enough. But if you're using a pay-as-you-go proxy, watch out for token consumption. I scanned 15 files and spent about 40,000 tokens, which is less than 2 RMB.
Limitations and Things to Note
After using it for a full day, I have to mention a few real downsides.
The choice of proxy API directly determines success or failure. I tried two proxies – the first had occasional 502 errors, the second was mostly stable. If your proxy connection quality is average, clawdfree will automatically retry, but you'll notice obvious lag. This is not a clawdfree issue; it's an upstream problem.
It does not support multi-user collaboration scenarios. Since it's essentially a modified version that bypasses subscriptions, if you need team collaboration, the official version's permission management and sharing features are still irreplaceable.
Model updates are lagging. It's based on v2.1.88. If the official version updates, clawdfree will need someone to modify it again to keep up. Currently, after comparison, the functionality is basically the same, but occasional differences in some tool invocations can be encountered.
Also: If you're used to Claude Code's deep thinking mode, it's enabled by default in clawdfree. However, some proxy providers don't handle long contexts well, dropping responses beyond 80K. So if the model suddenly can't give a conclusion, first check if the context has blown up.
Who Is It For?
Personally, I think clawdfree is best for two types of people: first, individual developers, especially during short-term projects or practice phases, who don't want to pay for a subscription just for one tool; second, those who already have existing proxy API Keys (e.g., bought some credits that are unused) – running clawdfree with them is almost zero cost.
However, if you are a formal team with many project files and require stability and continuity, I still recommend going with the official version. After all, the subscription money saved may be far less than the loss caused by a single proxy failure wasting time.
Lastly: clawdfree itself is free, has no built-in ads, and is just a modified command-line tool. Once you configure the API, you can use it directly. That's quite a good deal.
